Understanding post-operative refractive outcome in pediatrics after IOL implementation: factors and predictors.

BACKGROUND: In pediatric ophthalmology, calculating intra-ocular lens (IOL) power can be challenging. It is important to predict if the post-surgery refractive error (RE) will meet the intended refractive goal. In this study, we aimed to investigate the factors and predictors influencing RE outcomes in children undergoing IOL implantation. METHODS: This was a retrospective cross-sectional cohort study that involved 47 eyes with congenital cataracts underwent IOL implantation. Each patient underwent follow-up visits at two months and two years' post-surgery. The IOL power calculations were conducted using the Holladay 1 formula, and both the prediction error (PE) and absolute prediction error (APE) were calculated. RESULTS: The mean age was 6.52 ± 4.61 years, with an age range of 1-15 years. The mean IOL power was 20.31 ± 6.57 D, and the mean post-operative refraction was 1.31 ± 2.65 D. The mean of PE and APE were 0.67 ± 1.77 and 1.55 ± 1.06 D, respectively. Whereas PE was correlated to axial length with an R-value of - 0.29 (P = 0.04). The calculation method had a significant negative relationship with APE and PE, with coefficients of - 1.05 (P = 0.009) and - 1.81 (P = 0.009), respectively. CONCLUSION: High astigmatism was associated with greater errors in the refractive outcome. The calculation methods had the most considerable impact on the post-operative RE. The customization of surgical approaches to accommodate individual characteristics is crucial. Further research with diverse subgroups is needed to comprehensively understand the influence of each factor.

Design and Validation of Endophthalmitis Infectivity Measurement Algorithm in Post Cataract Acute Endophthalmitis: EMS Report No. 6.

Purpose: We constructed a clinical clue-based algorithm to identify the microbiology-positive post-cataract surgery endophthalmitis. Methods: The Endophthalmitis Infectivity Measurement Algorithm (EIMA) was constructed using presenting Snellen vision (Letter score [LS]) and Inflammation Score (IS, from the cornea, anterior chamber, iris, and vitreous). Retrospective data (70% for training; 30% for testing) was fitted into CHAID (Chi-squared Automatic Interaction Detection). EIMA was validated with prospective data. EIMA-categorized disease severity was weighed against the symptom duration to detect infecting micro-organisms. Results: EIMA was constructed from 1444 retrospective data. The average LS was 6.03 ± 12.11, median IS was 14 (8-24), and culture positivity was 38%. The accuracy and area under the curve of CHAID were 66.36% and 0.642, respectively. EIMA was validated with 175 prospectively collected data. Microbiology positivity (culture + sequencing) was 58.9%. EIMA sensitivity, specificity, and accuracy against microbiology-positive endophthalmitis were 73.7 (95% confidence interval [CI], 64.19-81.96), 81.9 (95% CI, 71.1-90.02), 77.1 (95% CI, 70.20-83.14), respectively. The positive and negative likelihood ratios were 4.08 (95% CI, 2.46-6.67) and 0.32 (95% CI, 0.22-0.45), respectively. There was higher microbial growth in two days or less than in three- to six-day symptom duration (69.9% vs. 28.2%; P = 0.018) endophthalmitis. Gram-negative infection was higher in two days or less (55.6% vs. 20.2%; P = 0.014), and gram-positive infection was higher in three- to six-day endophthalmitis (62.1% vs. 27.7%; P = 0.027). Conclusions: EIMA identified microbiology-positive endophthalmitis three-quarters of the time. Translational Relevance: EIMA suggested infectivity and the class of microbial infection could help targeted management of endophthalmitis after cataract surgery.

Two-year retrospective review of lens-induced glaucoma in Hospital Taiping, Perak, Malaysia.

INTRODUCTION: Delayed cataract surgery has long been known to cause lens-induced glaucoma (LIG). This study examined the demographic and clinical profile, ocular characteristics and outcomes of LIG in a tertiary referral centre in Malaysia. MATERIALS AND METHODS: Data from the National Eye Database (Malaysia) for cataract surgery performed at Hospital Taiping, Perak, between January 2019 and December 2020 were reviewed. The medical records of patients with LIG were retrieved to obtain demographic data, clinical profiles and visual outcomes. RESULTS: Of 3233 patients who underwent cataract surgery at Hospital Taiping, Perak, between 2019 and 2020, 25 underwent emergency surgery for LIG. However, only 24 patients fulfilling the diagnostic criteria for LIG were included in the study: 14 (58.33%) patients with phacomorphic and 10 (41.6%) patients with phacolytic glaucoma. The mean age of the patients was 66±12 years. Women and men were equally affected. Most patients were Malay (75%), followed by Chinese (16.67%) and Indian (8.33%). The anterior chamber depth (ACD) was significantly shallow with a mean value of 2.72 mm. Nineteen (79.1%) patients presented with visual acuity of worse than counting fingers. The mean intraocular pressure (IOP) at presentation was 47.5±13.66mmHg, which improved to 15.08±8.09mmHg postoperatively. A best-corrected visual acuity of 6/15 and better was achieved in 20 patients (83.33%) despite glaucomatous optic neuropathy being present in 41.67% of the cases. The majority (58.3%) of surgeries were performed via extracapsular cataract extraction, while six (25%) of our patients underwent successful phacoemulsification. Seven (29.17%) patients had intraocular complications: five with zonular dialysis and two with posterior capsule rupture. Of these seven cases, four ended up with intracapsular cataract extraction, leaving two of them aphakic. CONCLUSION: Prompt cataract surgery is paramount in all LIG cases to reduce IOP and achieve better visual outcomes. Despite the promising prognosis associated with early surgical intervention, patients should be counselled about the potential for a guarded visual prognosis from complicated surgery and its long-term complications.

The outcomes of paediatric cataract surgery with intraocular lens insertion in sub-Saharan Africa: a systematic review.

IMPORTANCE: Cataract is one of the leading causes of childhood blindness in Africa. The management of this condition requires timely surgical extraction of the cataractous lens with immediate optical correction and long-term follow-up to monitor visual improvement and manage complications that may arise. This review provides an opportunity to benchmark outcomes and to shed light on the reasons for those outcomes. OBJECTIVES: To review the published literature and report on the outcomes of paediatric cataract surgery with intraocular lens insertion in sub-Saharan Africa. DATA SOURCE: The EMBASE, PubMed, Scopus, and Web of Science were searched for relevant articles. STUDY SELECTION: We included all published primary studies from sub-Saharan Africa on cataract surgery outcomes in children aged 0-16 years with primary intraocular lens implantation conducted between 1990 and 2020. Eligible studies were those published in English or for which an English translation was available. In addition, reviewers screened the reference lists of all studies included in the full-text review for eligible studies. During the review, studies fitting the inclusion criteria above except for having been conducted in middle and high-income countries were tagged and placed in a comparison arm. DATA EXTRACTION AND SYNTHESIS: Study eligibility was determined by two independent reviewers, and data extraction was conducted by one reviewer with entries checked for accuracy by another reviewer. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines for data synthesis were followed. The Joanna Briggs Institute (JBI) critical appraisal checklist was used for quality appraisal of the studies. The statistical software R was used in the analysis, and data were pooled using a random-effects model. Forest plots were generated using the R package 'metafor'. MAIN OUTCOMES AND MEASURES: The primary outcome was visual acuity (VA) after cataract surgery and the proportions of eyes that achieved good, borderline, or poor visual outcome according to the World Health Organisation (WHO) categorisation of post-operative visual acuity. The secondary outcome measures reported included lag time to surgery, rates of follow-up, and rate of complications. RESULTS: Eight out of 4763 studies were eligible for inclusion in this review, and seven were included in the quantitative analysis. There was a male preponderance in the study population, and the mean age at the time of cataract surgery ranged from 3.4 to 8.4 years. Visual outcomes were available for short-term visual outcomes (1 to 6 months) as the studies had a significant loss to follow-up. The pooled proportion of eyes that achieved a good visual acuity (i.e. equal to or greater than 6/18) in the short-term period was 31% (CI, 20-42). The comparative studies from middle and high-income countries reported proportions ranging from 41 to 91%, with higher thresholds for good visual acuity of 6/12 and 6/15. CONCLUSION AND RELEVANCE: This review reports that there is a lower proportion of eyes with good outcomes after undergoing paediatric cataract surgery in sub-Saharan Africa than in middle- and high-income countries. Furthermore, this review states that there is a high proportion of patients lost to follow-up and suboptimal refractive correction and amblyopia treatment after paediatric cataract surgery.

POSTINTRAVITREAL INJECTION AND POSTCATARACT EXTRACTION ENDOPHTHALMITIS VISUAL OUTCOMES BY ORGANISM: A SYSTEMATIC REVIEW AND META-ANALYSIS.

PURPOSE: To compare visual outcomes of endophthalmitis following intravitreal injections (IVIs) and cataract extraction by causative organism. METHODS: Searches in Cochrane Central Register of Controlled Trials, MEDLINE, and Embase identified articles reporting visual outcomes by causative organisms in post-IVI and cataract extraction endophthalmitis cases from January 2010 to February 2022. A random-effects meta-analysis compared visual improvement among endophthalmitis cases caused by causative organisms. RESULTS: Eighty-five out of 3,317 retrieved studies were included. The highest degree of visual acuity improvement in both post-IVI and postcataract extraction endophthalmitis was seen in cases caused by coagulase-negative staphylococci, followed by gram-negative organisms and other gram-positive organisms such as streptococci and enterococci. Culture-negative cases showed more visual acuity improvement than culture-positive cases in post-IVI endophthalmitis. These results remained consistent when accounting for endophthalmitis treatment, IVI type, condition requiring IVI treatment, follow-up period, and initial preprocedural visual acuity. CONCLUSION: Coagulase-negative staphylococci and gram-negative organisms show the most visual acuity improvement in both post-IVI and postcataract extraction endophthalmitis. Other gram-positive organisms such as streptococci and enterococci are associated with less visual improvement. This updated systematic review and meta-analysis revealed that the results of the Endophthalmitis Vitrectomy Study are consistent decades later despite advancements in surgical practices and the evolution of microorganisms over time.

Comparative analysis of surgically induced astigmatism following cataract surgery: influence of previous myopic correction and corneal parameters.

PURPOSE: This retrospective study investigated the impact of corneal parameters on surgically induced astigmatism (SIA) in eyes with prior myopic correction undergoing cataract surgery. SETTING: Department of Ophthalmology, San Marino Hospital, San Marino, Republic of San Marino. DESIGN: This case-control study analyzed existing data retrospectively, without randomization or masking. METHODS: Eighty eyes divided in group 1 (40 eyes previous underwent refractive surgery for myopia) and group 2 ( 40 myopic eyes) that underwent cataract surgery with intraocular lens (IOL) implantation were included. SIA was calculated using values from the IOL Master Zeiss 700 and mean pupil power (MPP) derived from the CSO Sirius Topographer (based on 3 mm pupil size) with vectorial analysis from doctor Hill software. RESULTS: No significant difference in SIA was observed between eyes with prior myopic photorefractive keratectomy and the control group (p > 0.05). SIA calculations using the IOL Master and CSO Sirius Tomographer yielded similar results. There was no significant correlation between SIA and axial length, corneal curvature, peripheral corneal thickness, or anterior chamber depth (p > 0.05). However, an inverse correlation was found between SIA and horizontal corneal diameter (p < 0.05). CONCLUSIONS: Corneal parameters, such as axial length, corneal curvature, peripheral corneal thickness, and anterior chamber depth, showed no significant influence on SIA. The inverse correlation between SIA and horizontal corneal diameter in study group suggests potential influence of white-to-white distance on SIA. These findings highlight the importance of considering corneal parameters for optimizing surgical outcomes.

Nationwide incidence of and risk factors for undergoing incisional glaucoma surgery following infantile cataract surgery.

Nationwide incidence and risk factors for incisional glaucoma surgery post-infantile cataract (IC) surgery in children remain poorly understood. We conducted a population-based cohort study using the Korean national health claims database to identify IC patients diagnosed before age 1 who had IC surgery among all Korean born between 2008 and 2018 (n = 9,593,003). We estimated the annual occurrence of undergoing incisional glaucoma surgery following IC surgery in the general population aged 0-10. The risk factors for incisional surgery including systemic comorbidities and ophthalmic anomalies were analyzed by multivariable logistic regression. Of 650 patients who had undergone IC surgery with a mean (standard deviation [SD]) follow-up period of 6.2 (3.2) years, 92 (14.2%) were diagnosed with glaucoma following infantile cataract surgery (GFICS). Among them, 21 patients (22.8%) underwent incisional glaucoma surgery after a mean (SD) follow-up duration of 5.4 (2.8) years from the diagnosis of GFICS. Median (InterQuartile Range) age at incisional surgery was 4 (2,6) years old. Twenty of 21 patients (95.2%) underwent incisional glaucoma surgery within 3 years of diagnosis of GFICS. No factors, except younger age at glaucoma diagnosis (P = 0.03), were associated with undergoing incisional surgery. These findings can better understand the epidemiologic features and clinical courses of GFICS.

Comparative efficacy of 0.1% and 0.15% Sodium Hyaluronate on lipid layer and meibomian glands following cataract surgery: A randomized prospective study.

PURPOSE: To compare the efficacy of a 0.15% HA with that of 0.1% HA eye drops for DES after cataract surgery. METHODS: This study was double blinded, randomized and prospective study, and conducted in 69 participants (70 eyes) from Pusan National University Yangsan Hospital and executed from February 1, 2022 to November 30, 2022. Participants were adult cataract patients with normal lid position, not suffering from any other ocular disease and not meet the exclusion cirteria of clinical trial. Participants were randomly divided into two groups: 35 participants (17 males and 18 females) in the 0.1% HA group and 34 participants (19 males and 15 females) in the 0.15% HA group, receiving treatment six times daily for 6 weeks following cataract surgery. Subjective and objective assessments were performed at preoperative and postoperative visits, including ocular surface disease index score, tear break up time, corneal staining score, Schirmer's I test score, lipid layer thickness), meiboscore, and biochemical analysis of the eye drops. RESULTS: Throughout the study, the postoperative ocular surface disease index score was significantly lower in the group receiving 0.15% hyaluronic acid than in the group receiving 0.1% hyaluronic acid. Additionally, the postoperative ocular surface disease index score showed a significant positive correlation with the postoperative use of 0.15% hyaluronic acid and the preoperative Schirmer's I test score. In multivariate analysis, treatment with 0.15% hyaluronic acid and the preoperative ocular surface disease index score were significant independent parameters affecting the postoperative ocular surface disease index score. CONCLUSION: The use of 0.15% hyaluronic acid is recommended for its potential advantages in alleviating symptoms following cataract surgery, making it a viable alternative to traditional 0.1% hyaluronic acid treatment. TRIAL REGISTRATION: ISRCTN95830348.

Rare micropupil secondary to congenital cataract surgery favoring the development of the affected eye: a case report.

BACKGROUND: Congenital microcoria has been extensively reported and usually leads to visual dysfunction or blindness. However, micropupil development secondary to cataract surgery has never been reported. Here, we describe a rare case of micropupil development in infancy that occurred secondary to combined cataract extraction and intraocular lens implantation for treatment of congenital cataract. When the patient reached adulthood, the affected eye not only gained good vision but also showed better ocular development and refractive status than the fellow eye. CASE PRESENTATION: A 17-year-old boy presented to our outpatient clinic with decreased vision in his left eye related to congenital cataract surgery at 6 months of age. The affected eye had exhibited a pinhole pupil since the third month postoperatively. The condition had been managed with observation and regular monocular occlusion treatment. Upon presentation to our clinic, the best-corrected visual acuity (BCVA) in his fellow eye was 0.0 logMAR(20/20) with a refraction of - 5.75 diopters cylinder/-2.25 diopters sphere, and the BCVA in his affected eye was 0.5 logMAR(20/40) with a refraction of 0.00 diopters. Ophthalmic examination of the affected eye revealed a pinhole pupil (approximately 0.5 mm) with high light reflex sensitivity but no response to pupil-dilating drugs. The patient underwent pupilloplasty of the affected eye under corneal surface anesthesia. Postoperative examination revealed better ocular development in the affected eye than in the fellow eye (axial length: 24.21 vs. 27.02 mm, respectively) as well as better refractive status in the affected eye (BCVA of 0.0 logMAR(20/20) with a refraction of - 2.23 diopters cylinder/-3.00 diopters sphere vs. 0logMAR(20/20) with a refraction of -5.75 diopters cylinder/-2.25 diopters sphere). CONCLUSIONS: We have reported a rare case of micropupil development secondary to congenital cataract surgery, which is an uncommon complication, especially in children. However, unlike congenital microcoria, the secondary pinhole pupil may have reduced imaging haze and halos, possibly favoring the development of the affected eye. This case provides further insight into the treatment of congenital cataract.

Predictive biomarkers of intra-ocular pressure decrease after cataract surgery associated with trabecular washout in patients with pseudo exfoliative glaucoma.

To investigate biomarkers of intra-ocular pressure (IOP) decrease after cataract surgery with trabecular washout in pseudo-exfoliative (PEX) glaucoma. A single-center observational prospective study in PEX glaucoma patients undergoing cataract surgery with trabecular washout (Goniowash) was performed from 2018 to 2021. Age, gender, visual acuity, IOP, endothelial cell count, central corneal thickness, medications, were collected over 16-month follow-up. Multivariable binomial regression models were implemented. 54 eyes (35 subjects) were included. Mean preoperative IOP (IOPBL) was 15.9 ± 3.5 mmHg. Postoperative IOP reduction was significant at 1-month and throughout follow-up (p < 0.01, respectively). IOPBL was a predictive biomarker inversely correlated to IOP decrease throughout follow-up (p < 0.001). At 1 and 12 months of follow-up, IOP decrease concerned 31 (57.4%) and 34 (63.0%) eyes with an average IOP decrease of 17.5% (from 17.6 ± 3.1 to 14.3 ± 2.2 mmHg) and 23.0% (from 17.7 ± 2.8 to 13.5 ± 2.6 mmHg), respectively. Performance (AUC) of IOPBL was 0.85 and 0.94 (p < 0.0001, respectively), with IOPBL threshold ≥ 15 mmHg for 82.1% and 96.8% sensitivity, 84.2% and 75.0% specificity, 1.84 and 3.91 IOP decrease odds-ratio, respectively. All PEX glaucoma patients with IOPBL greater than or equal to the average general population IOP were likely to achieve a significant sustainable postoperative IOP decrease.

Poppers maculopathy missed in a patient with cataract highlights the importance of preoperative optical coherence tomography.

Poppers maculopathy is a complication of alkyl nitrate (poppers) inhalation. It presents with non-specific symptoms and variable signs, which can make it difficult to diagnose. We present a case of coexisting cataract and poppers maculopathy in a patient. He had vague visual symptoms that were attributed entirely to his cataract and he went on to have cataract surgery. Suboptimal postoperative visual acuity and normal clinical examination triggered further investigation with spectral-domain optical coherence tomography (SD-OCT), after which poppers maculopathy was diagnosed. We highlight the importance of performing OCT in the preoperative assessment of a cataract patient, especially where the cataract is mild and may not fully account for symptoms. The patient showed complete visual recovery on drug cessation despite ongoing maculopathy on OCT scans.

Intraoperative challenges and outcomes of pediatric cataract surgery following glaucoma filtering surgery.

PURPOSE: To analyze the intraoperative challenges of cataract surgery in children, following glaucoma filtering surgery. METHODS: This was a retrospective study to analyze intra-op challenges and outcomes of pediatric cataract surgery in post-glaucoma filtration surgery eyes, between January 2007 and December 2019. RESULTS: We included 20 eyes of 16 children. The most common glaucoma surgery performed was trabeculectomy and trabeculotomy (14 eyes). The median age at the time of cataract surgery was 74.5 months. The most common cataract surgery performed was lens aspiration with posterior chamber intraocular lens implantation (LA + PCIOL) (9/20). The most common intraoperative challenge faced was difficulty in capsulorrhexis (ten eyes), followed by extension of primary posterior capsulotomy (six eyes). At the final follow up eight eyes had improvement in visual acuity, five eyes had stable visual acuity and five eyes had a drop in visual acuity. In 12/20 eyes IOL was implanted, nine eyes in-the-bag and three eyes had in ciliary sulcus. None of the IOLs in the bag had decentration of IOL. The median postoperative IOP (p = 0.12) and median number of postoperative AGM (p = 0.13) at 2 years remained stable compared to the preoperative values. The IOP remained well controlled in 4 eyes without anti-glaucoma medications and in 14 eyes with anti-glaucoma medications and none needed additional surgery for IOP control. Two eyes developed retinal detachment postoperatively. CONCLUSION: Cataract surgery in pediatric eyes with prior glaucoma surgeries, have challenges with capsulorrhexis and IOL stability. The visual outcomes were reasonably good so was the IOP control.

Prophylactic Intracameral Antibiotics and Endophthalmitis After Cataract Surgery.

Importance: Although the effectiveness of intracameral antibiotics to prevent postoperative endophthalmitis is described, selective use of antibiotics combined with 1% povidone iodine disinfection might be equally effective and could lead to cost reduction and avoidance of unnecessary use of antibiotics. Objective: To compare the incidence of postoperative endophthalmitis when 1% povidone iodine disinfection is applied in combination with selective intracameral antibiotics with the incidence after routine use of intracameral antibiotics in combination with 5% povidone iodine. Design, Setting, and Participant: This was a retrospective cohort study using incidence data from the ongoing endophthalmitis register of the Rotterdam Eye Hospital, a specialized hospital providing both secondary and tertiary ophthalmological care, when intracameral antibiotics were used only during cataract procedures with occurrence of a posterior capsular tear in comparison with results from cohorts described in the literature where routine antibiotics were used. All patients who had cataract (phacoemulsification) surgery at the Rotterdam Eye Hospital between 1993 and 2022 were included. No cataract surgical procedures combined with other intraocular procedures were included. Exposure: Povidone iodine disinfection and intracameral antibiotics during cataract surgery either routinely or only in case of posterior capsular tears. Main Outcome and Measure: Postoperative endophthalmitis incidence. Results: Postoperative endophthalmitis incidence after 56 598 cataract (phacoemulsification) surgical procedures in the Rotterdam Eye Hospital between 2016 and 2022 was 0.000 (95% CI, 0.000-0.000). A PubMed literature search until September 2023 with respect to the incidence of postoperative endophthalmitis after routine antibiotic prophylaxis yielded 37 publications with an overall postoperative endophthalmitis incidence of 0.000 (95% CI, 0.000-0.000). Conclusions and Relevance: No difference was observed between the postoperative endophthalmitis incidence during the last 7 years in the Rotterdam Eye Hospital and the overall postoperative endophthalmitis incidence after routine intracameral antibiotics prophylaxis as described in the literature. Disinfection with 1% povidone iodine in combination with selective antibiotic prophylaxis may be equally effective as routine antibiotic use and 5% povidone iodine.

Crystalline keratopathy secondary to the use of ciprofloxacin after cataract surgery with confirmation by histopathological study: A case report and review of the literature.

OBJECTIVE: To report the case of a 75-year-old patient who presented crystalline keratopathy secondary to the use of topical ciprofloxacin with histopathological verification, after cataract surgery without complications. METHOD: Case report with clinical and photographic follow-up, as well as slides with samples of epithelium and crystalline deposits. RESULTS: Corneal deposits resolved after drug suspension, topical lubricant change, and subsequent surgical debridement. The histopathological examination reported epithelial cells and basophilic particles compatible with drug precipitates. CONCLUSIONS: Crystalline keratopathy is a condition in which crystals of various kinds are deposited in the corneal epithelium and/or in the anterior stroma. It may have an infectious, pharmacological cause or, in rarer cases, corneal dystrophies. Certain factors such as a previous epithelial defect, systemic pathology with diabetes mellitus, ocular surgery and previous dry eye can favor the deposition of ciprofloxacin leading to the formation of a keratopathy.

Reverse pupillary block with pigment dispersion and elevated intraocular pressure following bilateral phakic intraocular lens implantation.

The authors describe a case of reverse pupillary block with pigment dispersion following sequential phakic intraocular lens (pIOL) implantation for high myopia, in a young female patient. The intraocular pressure (IOP) elevation began 3 weeks postoperatively, for which Nd-YAG laser peripheral iridotomies (PIs) were attempted elsewhere. Despite maximum medical therapy, the IOP was uncontrolled. She was referred to our institute for further management. Examination showed anteriorly displaced iris-pIOL diaphragm, iris pigment dispersion and raised IOP. The PIs were incomplete. Based on clinical evaluation and investigations, we concluded that the excess area of contact of the posterior iris over the pIOL caused a reverse pupillary block and pigment dispersion. The IOPs were controlled by repeating laser iridotomies and with medical therapy. Subsequently, the patient developed a low lens vault leading to bilateral cataract. Sequential explantation of the pIOL along with cataract extraction was performed and her vision was restored.

NSAID-induced corneal melt as the first presentation of Sjögren's syndrome.

A non-diabetic woman in her 80s presented 1 week following uncomplicated left eye cataract surgery complaining of decreased vision, gritty sensation and photophobia in the same eye. Postoperative treatment included G. Acular (Ketorolac Tromethamine 0.5%, NSAID: non-steroidal anti-inflammatory drug) and G. Tobradex (Tobramycin 0.3% and Dexamethasone 0.1%, antibiotic and steroid, respectively) each prescribed four times a day for 2 weeks. On examination, the patient had a corneal epithelial defect which progressed to a full-thickness perforation despite ceasing the NSAID drops. Cyanoacrylate glue application with a plastic drape patch failed to seal the perforation, and a full-thickness tectonic corneal transplant was performed. On investigation, the patient had positive anti-RO and anti-LA antibodies, suggesting a diagnosis of Sjögren's syndrome. We advocate for careful preoperative assessment prior to cataract surgery, patient education, close follow-up and cautious medication use postoperatively including avoiding NSAID drops in patients with risk factors for postoperative dry eye disease.

Association Between Preoperative Ocular Parameters and Myopic Shift in Children Undergoing Primary Intraocular Lens Implantation.

Purpose: To evaluate the association between preoperative ocular parameters and myopic shift following primary intraocular lens (IOL) implantation in pediatric cataracts. Methods: Eyes from pediatric patients undergoing bilateral cataract surgery with primary IOL implantation were included. Eyes were grouped by age at surgery and subdivided into three axial length (AL) subgroups and three keratometry subgroups. Mixed-effects linear regression was utilized to assess the trend in myopic shift among subgroups. Multivariable analysis was performed to determine factors associated with myopic shift. Results: A total of 222 eyes were included. The median age at surgery was 4.36 years (interquartile range [IQR], 3.16-6.00 years) and the median follow-up was 4.18 years (IQR, 3.48-4.64 years). As preoperative AL increased, a decreased trend was observed in myopic shift and rate of myopic shift (P = 0.008 and P = 0.003, respectively, in the 4 to <6 years old group; P = 0.002 and P < 0.001, respectively, in the ≥6 years old group). Greater myopic shift and rate of myopic shift were associated with younger age at surgery (P = 0.008 and P = 0.008, respectively). Both myopic shift and rate of myopic shift were negatively associated with AL. Conclusions: Age at surgery and preoperative AL were associated with myopic shift in pediatric cataracts following primary IOL implantation. Adjusting the target refraction based on preoperative AL could potentially improve patients' long-term refractive outcome. Translational Relevance: This study may help to guide the selection of postoperative target refraction according to age at surgery and preoperative ocular parameters for pediatric cataracts.

Endophthalmitis after cataract surgery and effect of different intracameral antibiotic regimes in Sweden 2011-2017: national registry study.

PURPOSE: To study the incidence, predictive factors, etiology, and visual consequences of postoperative endophthalmitis (PE) in relation to 3 intracameral (IC) antibiotic regimes. SETTING: Swedish National Cataract Register entries from 2011 through 2017. DESIGN: Observational retrospective study. METHODS: PE incidence, influencing factors, bacteriology, and visual outcome were analyzed regarding the 3 major prophylactic IC protocols. RESULTS: The overall incidence of PE was 0.023% or 177 cases in 764 513 cataract procedures. Analyzed per IC regime, the rates of PE were 0.024% (126 cases in 514 916 surgeries) for cefuroxime, 0.020% (25 cases in 122 340 surgeries) for moxifloxacin, and 0.017% (20 cases in 121 045 surgeries) for combined cefuroxime-ampicillin. Incidences were not statistically significantly different from one another. Gram-positive bacteria caused 89.0% of culture positive cases. Enterococci as pathogens were significantly more frequent with IC cefuroxime than with moxifloxacin, P = .006, or cefuroxime-ampicillin, P < .001, while streptococci other than enterococci were more common with moxifloxacin than with cefuroxime, P < .001. Bacterial susceptibility to the given antibiotics was demonstrated in 21.3% of PE cases treated with cefuroxime, which was statistically significantly lower than proportions found with cefuroxime-ampicillin, 60.0%, P = .015, or with moxifloxacin, 88.2%, P < .001. Visual outcome worse than 20/200 was similar in the groups ranging from 42.0% to 53.7%. CONCLUSIONS: No statistically significant differences in PE incidence or visual outcome results between treatment groups were demonstrated. However, differences in etiology and bacterial sensitivity were found between the prophylactic IC treatments.

Incidence Rate of Secondary Glaucoma Following Congenital Cataract Surgery: An In-Depth Systematic Review and Meta-Analysis.

PURPOSE: To assess the incidence of secondary glaucoma in children following congenital cataract surgery. DESIGN: Systematic review and meta-analysis. METHODS: The PubMed, Embase, Cochrane Library, and Web of Science databases were searched from inception through March 16, 2023. Studies reporting congenital cataract surgery and glaucoma were enrolled. The quality of the selected studies was assessed using the Newcastle Ottawa Scale, and data analysis was executed utilizing R software. RESULTS: A total of 36 published studies with 3151 patients (4717 eyes) were included in the analysis. The incidence rate of glaucoma following congenital cataract surgery was 6.6% (95% CI: 3.9%, 9.9%). The incidence of secondary glaucoma in the primary intraocular lens (IOL) implantation group (3.3% [95% CI: 1.5%, 5.8%]) and the secondary IOL implantation group (3.5% [95% CI: 0%, 11.4%]) were lower compared to the aphakia group (13.5% [95% CI: 7.7%, 20.6%]). The incidence rate among children with congenital cataracts from Asia (6.9% [95% CI: 4.1%, 10.4%]) was higher than that in European children (0.9% [95% CI: 0%, 3.0%]; P < .01). A correlation was identified between the age at cataract surgery and the incidence of secondary glaucoma (P = .02). CONCLUSIONS: This meta-analysis found that the incidence of secondary glaucoma following congenital cataract surgery is approximately 6.6%. Children with IOL implantation exhibit a lower incidence of secondary glaucoma, with a lower incidence noted in European children compared to their Asian counterparts. The age at cataract surgery is an important risk factor to consider.

Vitreous hyper-reflective dots and the macular thickness after cataract surgery.

PURPOSE: To assess the association between vitreous hyper-reflective dots (VHD) and the macular thickness changes following uneventful phacoemulsification. METHODS: In this prospective cohort study optical coherence tomography (OCT) examinations were performed preoperatively and 1 week, 1 month and 3 months postoperatively in patients undergoing cataract surgery. OCT images were analyzed for retinal central subfield thickness (CST) and preretinal VHDs. Surgeries were recorded for the assessment of lens fragments in the space of Berger. RESULTS: 111 eyes of 97 patient were enrolled of whom 69 (62.2%) were female. VHDs were seen in 25 eyes (22.5%) at week 1; in 21 eyes (18.9%) at month 1 and in 3 eyes (2.7%) at month 3. In all eyes with VHDs retro-capsular lens fragments were visible immediately after phacoemulsification. The number of VHDs significantly decreased over the postoperative period. There was a moderate correlation between the number of VHDs and CST at 1 month (r = 0.426, p<0.001). In eyes with VHD the CST averaged 238.8±17.6 µm (214-266) at 1 week; 276.1±63.5 µm (231-481) at 1 month and 285.1±122.3 µm (227-785) at 3 months. In eyes with no detectable VHDs CST averaged 235.9±23.3 µm (192-311) at 1 week; 240.1±21.6 µm (200-288) at 1 month and 242.2±21.3 µm (205-289) at 3 months. Although the differences among the assessment points were relatively low, there was a significant difference in general (p<0.001, Friedman test). CONCLUSION: In conclusion, VHDs seem to cause macular thickening throughout the postoperative course. The origin of VHDs is still unknown; however, they presumably represent lens fragments that provoke subclinical inflammation.
